To ghost or confront?

I am a new FTM and haven't called my (former) bff since I went in to be induced 2 weeks ago. My bff volunteered to take care of our pets and went on and on about watching our dog and cat for us while we'd be in the hospital. But when the day came, she totally flaked. Not the first time this has happened. [She dropped out of our weddng 3 months before the day without saying anything].

My husband ended up having

to drive home to feed the cat 3x and pick up/drop our dog off at his mom's. He didn't miss the birth thankfully, but it did leave me with a ton of unnecessary anxiety.

She tried to call me while I was at the dr.'s (as usual) before going to the hospital, i texted her to let het know what was going on, and called her back once I was at the hospital. No answer. I texted her twice, no reply. But I checked Facebook messenger and it said she'd been active all evening.

The next day, the induction took so my water broke in the late am. She showed up totally unannounced at the hospital while I was having contractions. I told everyone ahead of time I only wanted my husband there until baby arrived. I didn't speak a word to her but heard her ask my husband if we still needed her to watch the dog- it's 2 pm, he would have had to go out well before then!

So ever since, I haven't really talked to her. I feel like she bailed on me after I've bent over backwards for her even through my tough pregnancy.

I feel like she's immature and self centered with zero concept of responsibility. She can't even make it to one college class on time. Her only concern is drinking and dating apps. She still lives at home, rent free, but complains about her dying mother not doing anything around the house and having to take care of her dogs.

She sent me a few text messages after my son was born telling me how happy she is for me and loves me multiple times trying to get me to say it back. I never did b/c I felt like if she really felt that way she would have kept her promise to help with our pets so we wouldn't have to worry about them. Her mom texted me for the first time and asked how we were doing. I received no explanation or apology from my friend, just generic concern.

But now I'm starting to feel bad for ghosting her. Mostly b/c I'm not sure if she knows why or just assumes that b/c I'm a mom now, I don't want anything to do w/ her. Which is not at all the case. I know I should be up front w/ her, but don't think it will accomplish anything b/c she's always full of excuses and self pity. I haven't decided if I want to keep her in my life or just let her go. This has been a one-way friendship for too long and I don't have time to sit and listen to all her self-made problems anymore.

Any ideas on how I should handle things?
